Hi, I just created a pull request for a couple of changes: https://github.com/apache/incubator-mynewt-larva/pull/11
0796ef2 <https://github.com/apache/incubator-mynewt-larva/commit/0796ef213444be48b59d31e378adca2efc61a3dc> : Support building "sim" with compiler optimization greater than -O0. This is interesting because the compiler actually emits useful warnings at higher levels. fb3520e <https://github.com/apache/incubator-mynewt-larva/commit/fb3520e2ca4aadc0d47928a0a54ebcd54a433f6e> : Fix a benign race in os_sched() where the task that is run next may not be the highest priority runnable task. Let me know if there are any comments and I'll be happy to iterate on the changes. best Neel
